The respite granted by the extreme temperatures after the peaks recorded in the Center-South on Friday, August 28 seems destined to end soon. Italy is preparing to face the sixth heat wave of the year. In fact, a resurgence of the subtropical anticyclone that has repeatedly hit the country during the summer of 2026 is expected, bringing a scorching and sultry climate. From Friday, September 4 to Wednesday, September 9, thermometers will rise up to eight degrees above seasonal averages. From Wednesday, however, the scenario will begin to change and from the following day rain and cooler air will arrive from Northern Europe.

The sixth wave
Despite extreme temperatures for this time of year, excessive anomalies will be spared by the calendar, which sees the days shorten and the hours in which cities are exposed to the sun progressively reduce. According to Lorenzo Tedici, media meteorologist at iLMeteo.it, the mercury columns will not exceed 37-38 degrees, while in mid-July an equivalent atmospheric configuration would have led to breaking the 41-42 degree barrier.
The heat wave bulletin from the Ministry of Health, in fact, shows a reduced number of orange and red alerts, which indicate potentially dangerous conditions for citizens’ health. On Thursday the 3rd, the maximum alert level is expected only in Bari and the only city in orange will be Cagliari. On Friday the 4th, instead, all 27 urban centers monitored by the bulletin will be marked with green and yellow alerts.

The real danger of yet another summer flare-up, however, as the meteorologist explains, will not lie so much in the immediate heat, but more in the energy stored over time: «The seas will continue to boil, turning into immense fuel tanks for the months to come,» explains Tedici.
